Eelco Dolstra e74113a305 Fix build-remote.pl
Apparently, turning on utf8 encoding on stderr changes its flushing
behaviour, causing sendReply to not send anything.

Eelco Dolstra a5c6347ff0 build-remote.pl: Use ‘nix-store --serve’ on the remote side
This makes things more efficient (we don't need to use an SSH master
connection, and we only start a single remote process) and gets rid of
locking issues (the remote nix-store process will keep inputs and
outputs locked as long as they're needed).

It also makes it more or less secure to connect directly to the root
account on the build machine, using a forced command
(e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix
daemon and is therefore more efficient.

Also, don't call nix-store to import the output paths.

Eelco Dolstra 1aa19b24b2 Add a flag ‘--check’ to verify build determinism
The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to
redo the build of a derivation whose output paths are already valid.
If the new output differs from the original output, an error is
printed.  This makes it easier to test if a build is deterministic.
(Obviously this cannot catch all sources of non-determinism, but it
catches the most common one, namely the current time.)

For example:

  $ nix-build '<nixpkgs>' -A patchelf
  ...
  $ nix-build '<nixpkgs>' -A patchelf --check
  error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv'

The --check build fails if not all outputs are valid.  Thus the first
call to nix-build is necessary to ensure that all outputs are valid.

The current outputs are left untouched: the new outputs are either put
in a chroot or diverted to a different location in the store using
hash rewriting.

Eelco Dolstra 0fdf4da0e9 Support cryptographically signed binary caches
NAR info files in binary caches can now have a cryptographic signature
that Nix will verify before using the corresponding NAR file.

To create a private/public key pair for signing and verifying a binary
cache, do:

  $ openssl genrsa -out ./cache-key.sec 2048
  $ openssl rsa -in ./cache-key.sec -pubout > ./cache-key.pub

You should also come up with a symbolic name for the key, such as
"cache.example.org-1".  This will be used by clients to look up the
public key.  (It's a good idea to number keys, in case you ever need
to revoke/replace one.)

To create a binary cache signed with the private key:

  $ nix-push --dest /path/to/binary-cache --key ./cache-key.sec --key-name cache.example.org-1

The public key (cache-key.pub) should be distributed to the clients.
They should have a nix.conf should contain something like:

  signed-binary-caches = *
  binary-cache-public-key-cache.example.org-1 = /path/to/cache-key.pub

If all works well, then if Nix fetches something from the signed
binary cache, you will see a message like:

  *** Downloading ‘http://cache.example.org/nar/7dppcj5sc1nda7l54rjc0g5l1hamj09j-subversion-1.7.11’ (signed by ‘cache.example.org-1’) to ‘/nix/store/7dppcj5sc1nda7l54rjc0g5l1hamj09j-subversion-1.7.11’...

On the other hand, if the signature is wrong, you get a message like

  NAR info file `http://cache.example.org/7dppcj5sc1nda7l54rjc0g5l1hamj09j.narinfo' has an invalid signature; ignoring

Signatures are implemented as a single line appended to the NAR info
file, which looks like this:

  Signature: 1;cache.example.org-1;HQ9Xzyanq9iV...muQ==

Thus the signature has 3 fields: a version (currently "1"), the ID of
key, and the base64-encoded signature of the SHA-256 hash of the
contents of the NAR info file up to but not including the Signature
line.

Issue #75.

Eelco Dolstra 2d9bb56e55 Fix segfault on Darwin
Ever since SQLite in Nixpkgs was updated to 3.8.0.2, Nix has randomly
segfaulted on Darwin:

  http://hydra.nixos.org/build/6175515
  http://hydra.nixos.org/build/6611038

It turns out that this is because the binary cache substituter somehow
ends up loading two versions of SQLite: the one in Nixpkgs and the
other from /usr/lib/libsqlite3.dylib.  It's not exactly clear why the
latter is loaded, but it appears to be because WWW::Curl indirectly loads
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation,
which in turn seems to load /usr/lib/libsqlite3.dylib.  This leads to
a segfault when Perl exits:

  #0  0x00000001010375f4 in sqlite3_finalize ()
  #1  0x000000010125806e in sqlite_st_destroy ()
  #2  0x000000010124bc30 in XS_DBD__SQLite__st_DESTROY ()
  #3  0x00000001001c8155 in XS_DBI_dispatch ()
  ...
  #14 0x0000000100023224 in perl_destruct ()
  #15 0x0000000100000d6a in main ()
  ...

The workaround is to explicitly load DBD::SQLite before WWW::Curl.

that instead.

Also, don't source ~/.bashrc in a non-interactive shell (detectable by

This reverts commit 69b8f9980f.

The timeout should be enforced remotely.  Otherwise, if the garbage
collector is running either locally or remotely, if will block the
build or closure copying for some time.  If the garbage collector
takes too long, the build may time out, which is not what we want.
Also, on heavily loaded systems, copying large paths to and from the
remote machine can take a long time, also potentially resulting in a
timeout.

This operation allows fixing corrupted or accidentally deleted store

Since the corrupted path cannot be replaced atomically, there is a

repairing should be used with some care on critical packages like
Glibc.

Eelco Dolstra 66a3ac6a56 Allow a binary cache to declare that it doesn't support "nix-env -qas"
Querying all substitutable paths via "nix-env -qas" is potentially
hard on a server, since it involves sending thousands of HEAD
requests.  So a binary cache must now have a meta-info file named
"nix-cache-info" that specifies whether the server wants this.  It
also specifies the store prefix so that we don't send useless queries
to a binary cache for a different store prefix.

In "nix-env -qas", we don't need the substitute info, we just need to

saves bandwidth.

Note however that curl currently has a bug that prevents it from
reusing HTTP connections if HEAD requests return a 404:

https://sourceforge.net/tracker/?func=detail&aid=3542731&group_id=976&atid=100976

Without the patch attached to the issue, using HEAD is actually quite
a bit slower than GET.

Eelco Dolstra 11800e6198 download-from-binary-cache: parallelise fetching of NAR info files
Getting substitute information using the binary cache substituter has
non-trivial latency overhead.  A package or NixOS system configuration
can have hundreds of dependencies, and in the worst case (when the
local info cache is empty) we have to do a separate HTTP request for
each of these.  If the ping time to the server is t, getting N info
files will take tN seconds; e.g., with a ping time of 0.1s to
nixos.org, sequentially downloading 1000 info files (a typical NixOS
config) will take at least 100 seconds.

To fix this problem, the binary cache substituter can now perform
requests in parallel.  This required changing the substituter
interface to support a function querySubstitutablePathInfos() that
queries multiple paths at the same time, and rewriting queryMissing()
to take advantage of parallelism.  (Due to local caching,
parallelising queryMissing() is sufficient for most use cases, since
it's almost always called before building a derivation and thus fills
the local info cache.)

For example, parallelism speeds up querying all 1056 paths in a
particular NixOS system configuration from 116s to 2.6s.  It works so
well because the eccentricity of the top-level derivation in the
dependency graph is only 9.  So we only need 10 round-trips (when
using an unlimited number of parallel connections) to get everything.

Currently we do a maximum of 150 parallel connections to the server.
Thus it's important that the binary cache server (e.g. nixos.org) has
a high connection limit.  Alternatively we could use HTTP pipelining,
but WWW::Curl doesn't support it and libcurl has a hard-coded limit of
5 requests per pipeline.
2012-07-06 19:08:20 -04:00
Eelco Dolstra cd94665f38 download-from-binary-cache: use WWW::Curl
Using WWW::Curl rather than running an external curl process for every
NAR info file halves the time it takes to get info thanks to libcurl's
support for persistent HTTP connections.  (We save a roundtrip per
file.)  But the real gain will come from using parallel and/or
pipelined requests.

Eelco Dolstra 4911a10a4e Use XZ compression in binary caches
XZ compresses significantly better than bzip2.  Here are the
compression ratios and execution times (using 4 cores in parallel) on
my /var/run/current-system (3.1 GiB):

  bzip2: total compressed size 849.56 MiB, 30.8% [2m08]
  xz -6: total compressed size 641.84 MiB, 23.4% [6m53]
  xz -7: total compressed size 621.82 MiB, 22.6% [7m19]
  xz -8: total compressed size 599.33 MiB, 21.8% [7m18]
  xz -9: total compressed size 588.18 MiB, 21.4% [7m40]

Note that compression takes much longer.  More importantly, however,
decompression is much faster:

  bzip2: 1m47.274s
  xz -6: 0m55.446s
  xz -7: 0m54.119s
  xz -8: 0m52.388s
  xz -9: 0m51.842s

The only downside to using -9 is that decompression takes a fair
amount (~65 MB) of memory.

Eelco Dolstra 49cd7387ad nix-push: create a manifest-less binary cache
Manifests are a huge pain, since users need to run nix-pull directly
or indirectly to obtain them.  They tend to be large and lag behind
the available binaries; also, the downloaded manifests in
/nix/var/nix/manifest need to be in sync with the Nixpkgs sources.  So
we want to get rid of them.

The idea of manifest-free operation works as follows.  Nix is
configured with a set of URIs of binary caches, e.g.

  http://nixos.org/binary-cache

Whenever Nix needs a store path X, it checks each binary cache for the
existence of a file <CACHE-URI>/<SHA-256 hash of X>.narinfo, e.g.

  http://nixos.org/binary-cache/bi1gh9...ia17.narinfo

The .narinfo file contains the necessary information about the store
path that was formerly kept in the manifest, i.e., (relative) URI of
the compressed NAR, references, size, hash, etc.  For example:

  StorePath: /nix/store/xqp4l88cr9bxv01jinkz861mnc9p7qfi-neon-0.29.6
  URL: 1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2
  CompressedHash: sha256:1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd
  CompressedSize: 202542
  NarHash: sha256:1af26536781e6134ab84201b33408759fc59b36cc5530f57c0663f67b588e15f
  NarSize: 700440
  References: 043zrsanirjh8nbc5vqpjn93hhrf107f-bash-4.2-p24 cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13 ...
  Deriver: 4idz1bgi58h3pazxr3akrw4fsr6zrf3r-neon-0.29.6.drv
  System: x86_64-linux

Nix then knows that it needs to download

  http://nixos.org/binary-cache/1bjxbg52l32wj8ww47sw9f4qz0r8n5vs71l93lcbgk2506v3cpfd.nar.bz2

to substitute the store path.

Note that the store directory is omitted from the References and
Deriver fields to save space, and that the URL can be relative to the
binary cache prefix.

This patch just makes nix-push create binary caches in this format.
The next step is to make a substituter that supports them.

Michel Alexandre Salim 6a214f3e06 Update nix profile: - incorporate NixOS's configuration so that nix is usable by normal users - install as a data file, not a program file 2012-05-31 08:59:36 -04:00
Eelco Dolstra 6814b1dfa1 Generate binary tarballs for installing Nix
For several platforms we don't currently have "native" Nix packages
(e.g. Mac OS X and FreeBSD).  This provides the next best thing: a
tarball containing the closure of Nix, plus a simple script
"nix-finish-install" that initialises the Nix database, registers the
paths in the closure as valid, and runs "nix-env -i /path/to/nix" to
initialise the user profile.

The tarball must be unpacked in the root directory.  It creates
/nix/store/... and /usr/bin/nix-finish-install.  Typical installation
is as follows:

  $ cd /
  $ tar xvf /path/to/nix-1.1pre1234_abcdef-x86_64-linux.tar.bz2
  $ nix-finish-install
  (if necessary add ~/.nix-profile/etc/profile.d/nix.sh to the shell
  login scripts)

After this, /usr/bin/nix-finish-install can be deleted, if desired.

The downside to the binary tarball is that it's pretty big (~55 MiB
for x86_64-linux).

Eelco Dolstra 59a26360c7 Support mandatory system features in the build hook
Mandatory features are features that MUST be present in a derivation's

testing, where we have a dedicated machine to run performance tests
(and nothing else).  Then we would add the label "perf" to the
machine's mandatory features and to the performance testing
derivations.

Eelco Dolstra e855c7e2c9 nix-channel improvements
"nix-channel --add" now accepts a second argument: the channel name.
This allows channels to have a nicer name than (say) nixpkgs_unstable.
If no name is given, it defaults to the last component of the URL
(with "-unstable" or "-stable" removed).

Also, channels are now stored in a profile
(/nix/var/nix/profiles/per-user/$USER/channels).  One advantage of
this is that it allows rollbacks (e.g. if "nix-channel --update" gives
an undesirable update).

Eelco Dolstra 5144abe5b6 Add an option "--exclude" to filter dependencies in "nix-build --run-env"
Sometimes when doing "nix-build --run-env" you don't want all
dependencies to be built.  For instance, if we want to do "--run-env"
on the "build" attribute in Hydra's release.nix (to get Hydra's build
environment), we don't want its "tarball" dependency to be built.  So
we can do:

  $ nix-build --run-env release.nix -A build --exclude 'hydra-tarball'

This will skip the dependency whose name matches the "hydra-tarball"
regular expression.  The "--exclude" option can be repeated any number
of times.

Eelco Dolstra 3e94ffffd6 Allow the command executed by "nix-build --run-env" to be overriden with --command 2012-03-27 11:16:43 +02:00
Eelco Dolstra 7f38087f35 Add a command "nix-build --run-env" to reproduce the environment of a derivation
This command builds or fetches all dependencies of the given
derivation, then starts a shell with the environment variables from
the derivation.  This shell also sources $stdenv/setup to initialise
the environment further.

The current directory is not changed.  Thus this is a convenient way
to reproduce a build environment in an existing working tree.

Existing environment variables are left untouched (unless the
derivation overrides them).  As a special hack, the original value of
$PATH is appended to the $PATH produced by $stdenv/setup.

Example session:

$ nix-build --run-env '<nixpkgs>' -A xterm
(the dependencies of xterm are built/fetched...)
$ tar xf $src
$ ./configure
$ make
$ emacs
(... hack source ...)
$ make
$ ./xterm

Eelco Dolstra 5bbd693cae * Add an API function exportPaths() that provides the functionality of
‘nix-store --export’.
* Add a Perl module that provides the functionality of
  ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
  longer needs to start a separate nix-copy-closure process.  Also, it
  uses the Perl API to do the export, so it doesn't need to start a
  separate nix-store process either.  As a result, nix-copy-closure
  and build-remote.pl should no longer fail on very large closures due
  to an "Argument list too long" error.  (Note that having very many
  dependencies in a single derivation can still fail because the
  environment can become too large.  Can't be helped though.)

Eelco Dolstra f8e609c341 * nix-pull: update the Nix manifest cache if necessary. Also, don't

2011-08-17 14:17:19 +00:00
Eelco Dolstra 1ecc97b6bd * Add a Nix expression search path feature. Paths between angle
brackets, e.g.

    import <nixpkgs/pkgs/lib>

  are resolved by looking them up relative to the elements listed in
  the search path.  This allows us to get rid of hacks like

    import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

  The search path can be specified through the ‘-I’ command-line flag
  and through the colon-separated ‘NIX_PATH’ environment variable,
  e.g.,

    $ nix-build -I /etc/nixos ...

  If a file is not found in the search path, an error message is
  lazily thrown.

Eelco Dolstra e649f3168b * Fix concurrency issues in download-using-manifests' handling of the

Eelco Dolstra 412914d004 * Read manifests directly into the database, rather than first reading

Eelco Dolstra 5591fcc529 * Cache the manifests in /nix/var/nix/manifests in a SQLite database.
This significantly speeds up the download-using-manifests
  substituter, especially if manifests are very large.  For instance,
  one "nix-build -A geeqie" operation that updated four packages using
  binary patches went from 18.5s to 1.6s.  It also significantly
  reduces memory use.

  The cache is kept in /nix/var/nix/manifests/cache.sqlite.  It's
  updated automatically when manifests are added to or removed from
  /nix/var/nix/manifests.  It might be interesting to have nix-pull
  store manifests directly in the DB, rather than storing them as
  separate flat files, but then we would need a command line interface
  to delete manifests from the DB.

Eelco Dolstra f42a505ab7 * Add a script `nix-generate-patches'.
* Fix the binary patching test.
2010-12-05 17:36:02 +00:00
Eelco Dolstra d3bba0c2d8 * Move the patch generator into a module. 2010-11-29 15:26:28 +00:00
Eelco Dolstra 9737a7eba0 * Don't generate patches if the system type differs. 2010-11-29 09:26:05 +00:00
Eelco Dolstra bd48fd97f6 * Impose a configurable time limit on patch generation. This is
necessary because bsdiff has some pathological worst-case behaviour,
  e.g. O(n^2) on files consisting only of 0s.
2010-11-29 09:15:45 +00:00
Eelco Dolstra 1a211d812f * Oops. 2010-11-17 17:54:49 +00:00
Eelco Dolstra a4f0365b2d * When checking whether a patch is applicable, for efficiency, use
`nix-store -q --hash' to get the hash of the base path rather than
  `nix-hash'.  However, only do this for estimating the size of a
  download, not for the actual substitution, because sometimes the
  contents of store paths are modified (which they shouldn't, of
  course).
2010-11-17 17:41:59 +00:00
Eelco Dolstra 3d38a49840 * In the download size indication, take binary patches into account.
Hopefully this doesn't slow things down too much.
2010-11-17 17:32:25 +00:00
Eelco Dolstra bdf089f463 * Before a build, show the disk space that the downloaded store paths
will approximately require.
2010-11-17 14:31:42 +00:00
Eelco Dolstra 06699d4219 * Store the NAR size in the manifest. 2010-11-17 12:57:52 +00:00
Eelco Dolstra 5693b8a7e2 * nix-push: no need to compute the NAR hash, since the Nix database
already has it (`nix-store -q --hash').
2010-11-17 12:51:54 +00:00
Eelco Dolstra bfa6ee7d91 * Don't use SSH's `-tt' flag because it doesn't seem to work
on OpenSolaris when using connection sharing.  Instead have
  the remote side check for disconnection and kill the process 
  group when that happens.
2010-10-04 12:30:46 +00:00
Eelco Dolstra bf0dde9597 * Always print hook output on stderr, even if --no-build-output is
set.
* In the build hook, print a trace message to allow Hydra to pick up
  the name of the remote machine used for the build.
2010-08-31 12:36:24 +00:00
Eelco Dolstra 80e722278c * When using the build hook, distinguish between the stderr of the
hook script proper, and the stdout/stderr of the builder.  Only the
  latter should be saved in /nix/var/log/nix/drvs.
* Allow the verbosity to be set through an option.
* Added a flag --quiet to lower the verbosity level.
2010-08-30 14:53:03 +00:00
Eelco Dolstra 766f708418 * Experimental feature: allow a derivation to tell the build hook that
it requires a certain feature on the build machine, e.g.

    requiredSystemFeatures = [ "kvm" ];

  We need this in Hydra to make sure that builds that require KVM
  support are forwarded to machines that have KVM support.  Probably
  this should also be enforced for local builds.
2010-08-27 13:18:13 +00:00
Eelco Dolstra e437b08250 * Made the build hook mechanism more efficient. Rather than starting
the hook every time we want to ask whether we can run a remote build
  (which can be very often), we now reuse a hook process for answering
  those queries until it accepts a build.  So if there are N
  derivations to be built, at most N hooks will be started.
2010-08-25 20:44:28 +00:00
Eelco Dolstra 1a396f3789 * Don't call "cat". 2010-08-25 12:19:30 +00:00
Eelco Dolstra 95deba581d * In the build hook, temporarily register the derivation and its
output as GC roots.  This prevents a race if the garbage collector
  is running during the build.
2010-08-25 11:54:11 +00:00
Eelco Dolstra 1e5f5ea2e9 * Correctly handle SSH failing to establish a connection. Because
this didn't work right, the build hook wouldn't fall back to using
  other machines of the desired type.
2010-08-24 14:27:07 +00:00
Eelco Dolstra 5f9aad44ca * nix-build: recognise --cores. 2010-08-11 15:28:02 +00:00
Eelco Dolstra 587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00
Eelco Dolstra 532d766c27 * Don't barf if the source NAR for a patch has disappeared. 2010-07-21 11:30:23 +00:00
Eelco Dolstra 560ab22f7d * Ignore packages that don't have a version.
* Work on a manifest instead of a channel directory.
2010-06-23 21:11:33 +00:00
Eelco Dolstra 87ef5907e9 * Sync. 2010-06-22 14:42:34 +00:00
Eelco Dolstra 819548d92f * Pass `--fallback' to the remote build to ignore failing
substituters.
2010-06-22 14:41:22 +00:00
Eelco Dolstra c778ed1768 * Fix the copy-from-other-stores substituter. 2010-04-26 13:39:55 +00:00
Eelco Dolstra 05fbf61f0e * nix-prefetch-url depends on sed (see
http://hydra.nixos.org/build/311170).
2010-03-05 18:26:47 +00:00
Eelco Dolstra 68e55cd9da * Since Hydra now escapes +', =' and `?' to %NN in URIs,
nix-prefetch-url should unescape them, because `%' is not a valid
  character in store path names.
2010-02-16 00:10:39 +00:00
Eelco Dolstra 719cebcac2 * "Fix" incorrect help message. 2010-02-04 09:38:09 +00:00
Eelco Dolstra 443673620d * Don't use ssh's -f flag since it leads to lots of lingering ssh
processes.
2010-02-04 02:38:40 +00:00
Eelco Dolstra 7ec5a65925 * Doh! The scope of $slotLock should extend to the end of the script,
because otherwise the lock will be released at the end of the while
  loop.
2010-02-04 02:18:29 +00:00
Eelco Dolstra c9b2d80bcd * Typo. 2010-02-04 02:05:34 +00:00
Eelco Dolstra 3cfe65e516 * Doh! Calling `system' in an END block causes the exit status in $?
to be changed to 0.
2010-02-04 02:05:22 +00:00
Eelco Dolstra e51a276907 * Remove the `cat' calls when not using --gzip. 2010-02-04 01:39:23 +00:00
Eelco Dolstra 408913bbaf * Revert r19796 for now. 2010-02-04 00:12:57 +00:00
Eelco Dolstra c45de33c67 * Respect @sysconfdir@. 2010-02-03 21:13:37 +00:00
Eelco Dolstra d0c32dc135 * In the build hook, if connecting to a machine fails, try the other
machines of the right type (if available).  This makes the build
  farm more robust to failures.
2010-02-03 20:35:37 +00:00
Eelco Dolstra f56a039775 * Use SSH connection sharing in the remote build script.
* Removed the Cygwin password hack since the problem is apparently
  fixed in Visual Studio.
2010-02-03 20:12:18 +00:00
Eelco Dolstra bc1e478db1 * nix-copy-closure: start only one SSH connection to the server, or
recycle an already existing connection (using  OpenSSH's connection
  sharing feature).
2010-02-03 15:34:52 +00:00
Eelco Dolstra e839802720 * Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't
support deleting the current directory.
2010-02-02 15:29:18 +00:00
Eelco Dolstra 50e34891f0 * Disable gzip compression in build-remote.pl because it puts too much
load on the Hydra build farm (where it's unnecessary anyway because
  it has a fast connection to the build machines).  In any case,
  compression can be enabled by using the `-C' option to ssh.
2010-01-25 16:14:45 +00:00
Eelco Dolstra 7ca9972636 * When doing a nix-pull, remove old manifests downloaded from the same
URL.  This prevents lots of old cruft accumulating in
  /nix/var/nix/manifests.
2009-12-09 19:36:54 +00:00
Eelco Dolstra c4c84d1edb * nix-build: be less verbose. 2009-12-09 18:08:28 +00:00
Eelco Dolstra 997db91e07 * Don't pass -K. It should really inherit the setting of the calling
Nix though.
2009-11-17 16:22:39 +00:00
Eelco Dolstra 3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.
2009-11-13 10:08:31 +00:00
Eelco Dolstra e1df4ef73c 2009-09-17 17:02:14 +00:00
Eelco Dolstra 86408b3f47 * build-remote.pl: Pick machines in a round-robin order, rather than
giving jobs to the first machine until it hits its job limit, then
  the second machine and so on.  This should improve utilisation of
  the Hydra build farm a lot.  Also take an optional speed factor
  into account to cause fast machines to be preferred over slower
  machines with a similar load.
2009-09-17 15:48:17 +00:00
Eelco Dolstra 57e0d73c77 * build-remote.pl: allow the system type to be a comma-separated list
of system types.  Don't treat the x86_64-linux system type
  specially.
2009-09-17 13:51:04 +00:00
Eelco Dolstra 20b6f94b65 * nix-build: pass the --show-trace flag. 2009-07-15 09:10:38 +00:00
Eelco Dolstra f24cf5d303 * nix-build: if nix-instantiate or nix-store fails due to a signal
(e.g. out of memory or a segfault), print an error message.
  Otherwise the user doesn't see anything.
2009-06-10 11:30:34 +00:00
Eelco Dolstra c710fe540e * Machines of type x86_64-linux can do i686-linux builds. 2009-04-21 12:42:47 +00:00
Eelco Dolstra 0460ea4c39 * Cleanup. 2009-04-16 09:27:33 +00:00
Eelco Dolstra 096affb55b * Update the mtime on the lock file to make it easy to see when a slot
was last used.
2009-03-29 18:40:44 +00:00
Eelco Dolstra 737423a89c * Use polling to wait for a remote build slot when using a build hook
(that is, call the build hook with a certain interval until it
  accepts the build).
* build-remote.pl was totally broken: for all system types other than
  the local system type, it would send all builds to the *first*
  machine of the appropriate type.
2009-03-29 18:00:45 +00:00
Eelco Dolstra 47706e3924 * nix-copy-closure: compute the closure in one call to nix-store,
which is much faster.
2009-03-28 21:10:29 +00:00
Eelco Dolstra 3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).
2009-03-28 19:29:55 +00:00
Eelco Dolstra 7fb548aa26 * Clean up the output a bit. 2009-03-28 16:12:46 +00:00
Eelco Dolstra 7e05b8b75e * Future proofing: assume we can read manifests up to version 10
(which should therefore be backwards compatible).
2009-03-19 10:02:02 +00:00
Eelco Dolstra b88460bcbc * Disregard the Hash field in manifests. 2009-03-19 09:47:34 +00:00
Eelco Dolstra 2897286487 * Unify exportReferencesGraph and exportBuildReferencesGraph, and make
sure that it works as expected when you pass it a derivation.  That
  is, we have to make sure that all build-time dependencies are built,
  and that they are all in the input closure (otherwise remote builds
  might fail, for example).  This is ensured at instantiation time by
  adding all derivations and their sources to inputDrvs and inputSrcs.
2009-03-18 17:36:42 +00:00
Eelco Dolstra 1dcf208f56 * Clean up some tests (use nix-build where appropriate). 2009-03-18 13:15:55 +00:00
Eelco Dolstra 1273d355ac * nix-install-package: don't pollute /nix/var/nix/manifests. 2009-02-27 14:06:38 +00:00
Eelco Dolstra d4ca5c3952 * Use the regular progress bar; the hash bar isn't very useful when
the size of the download isn't known in advance.
2009-02-27 13:55:11 +00:00
Eelco Dolstra fd2e14b3c8 * nix-build: support --option. 2009-02-27 12:09:30 +00:00
Eelco Dolstra 8ab6bc5a49 * nix-channel: use nix-build. 2009-02-27 11:01:03 +00:00
Eelco Dolstra f052c10eed * Check the manifest version. 2009-02-27 09:53:58 +00:00
Eelco Dolstra a7cee528c5 * Handle base-16 hashes in manifests. 2009-02-26 21:12:35 +00:00
Eelco Dolstra 041717eda3 * download-using-manifests: don't check the cryptographic hash of
downloaded files; rather, check the hash of the unpacked store
  path.

  When the server produces bzipped NAR archives on demand (like Hydra
  does), the hash of the file is not known in advance; it's streamed
  from the server.  Thus the manifest doesn't contain a hash for the
  bzipped NAR archive.  However, the server does know the hash of the
  *uncompressed* NAR archive (the "NarHash" field), since it's stored
  in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
  that instead for checking the integrity of the download.

Eelco Dolstra 1bb0f1e84b * Build hook: compress the transferred data. 2009-02-03 10:34:15 +00:00
Eelco Dolstra b682fae9d9 * Build hooks: use nix-store --import. This prevents a redundant
scan for runtime dependencies (i.e. the local machine shouldn't do a
  scan that the remote machine has already done).  Also pipe directly
  into `nix-store --import': don't use a temporary file.
2009-02-02 17:24:10 +00:00
Eelco Dolstra 019176137f * When using a build hook, distinguish between transient failures
(e.g. an SSH connection problem) and permanent failures (i.e. the
  builder failed).  This matters to Hydra (it wants to know whether it
  makes sense to retry a build).
